Managing diabetes requires a comprehensive approach, including lifestyle changes, regular monitoring, and sometimes medication. Among the various medications available, Sulfonylureas like Glipizide and Gliclazide play a significant role in controlling blood sugar levels. Let's delve into their mechanism of action, benefits, recommended dosages, and considerations for prescribing in the treatment of diabetes.
Understanding the Mechanism of Sulfonylureas
Sulfonylureas work by blocking potassium from leaving beta cells in the pancreas. This blockage causes changes in the cell's electrical charge, which then allows calcium to enter the cells. The influx of calcium triggers the release of insulin. This process triggers insulin release and also reduces hepatic glucose production, thereby reducing blood glucose levels. However, these medications are effective only in patients with functioning pancreatic beta cells. Additionally, these medications help reduce the amount of glucose produced by the liver.
The Benefits at a Glance
Sulfonylureas contribute to effective glycaemic control by lowering blood glucose levels. Their rapid onset of action makes them suitable for managing acute hyperglycaemia. Furthermore, their oral administration and simple dosing schedule enhance patient adherence to treatment.
Dosage Recommendations
For Glipizide, the usual starting dose is 5 mg taken orally before meals. The maximum dose typically doesn't exceed 20 mg per day. For Gliclazide, the initial dose usually stands at 40 mg taken once daily, which can be increased based on individual response. The maximum dose can go up to 320 mg per day.
Prescribing Considerations
Sulfonylureas can cause hypoglycaemia, particularly among elderly patients or those with irregular eating patterns or renal impairment. Patients may also experience weight gain, and cardiac issues while on sulfonylureas. Moreover, caution should be exercised when prescribing alongside other drugs that may interact with sulfonylureas (these are no longer recommended unless cost is constrained).

Aerobic or Resistance Exercises: Which One is Ideal to Manage Blood Sugar?
The American Diabetes Association recommends a combination of aerobic exercises like brisk walking or cycling (at least 150 minutes per week) and resistance training like weightlifting (2-3 sessions per week) for people with diabetes. Aerobic exercises help lower blood sugar by using glucose for energy and improving insulin sensitivity, while resistance exercises improve muscle strength and promote glucose uptake, aiding in blood sugar control.
